Abstract: A method and apparatus for preparing foundry moulds or cores from a cold-setting sand based foundry mixture. The foundry mixture is introduced to a mould or core box and during setting of the mixture in the box suction is applied to the box to accelerate the setting time.

Abstract: A method and apparatus for filling a foundry mould or core box with a sand-based foundry moulding mixture. The mixture is blown into the box under pressure while suction is applied to the box.

Abstract: An automatic method and apparatus for producing molds using chemically bonded sands which consists of a molding machine adapted to produce either honeycomb (horizontally parted) or controlled contour (vertically parted) mold elements. The molding machine is provided with a venturi-type blow head having dual blow valves and an integral air chamber. Carriage means are provided to selectively move a sand magazine and catalyst manifold between their respective fill and work stations on the molding machine. A hydraulically actuated mold receiver, trunnion rollover and shuttle car means are provided to selectively receive the completed molds from the molding machine and transport them to associated mold finishing and closing means. A hydraulically actuated pattern clamp table is provided with an enclosed pattern and stripper pin stool having a separate hydraulically actuated stripper pin plate. The enclosed pattern and stripper pin stool is an integral catalyst exhaust manifold.

Abstract: A cyclicly-operable molding machine for producing and assembling cope and drag mold parts.
